Typical Applications
TPS63070RNMT is suitable for 6 applications: Battery-Powered Portable Devices, Industrial Sensors and Automation, IoT and Smart Home Devices, Automotive Electronics, Renewable Energy Systems, Test and Measurement Equipment.
Battery-Powered Portable Devices
The TPS63070RNMT is ideal for battery-powered devices such as smartphones, tablets, and portable medical devices. Its wide input voltage range (2V-16V) allows it to regulate output voltage as the battery discharges, ensuring stable operation. With a low quiescent current of 50uA and high efficiency, it extends battery life. For example, a 2-cell Li-ion battery (6V-8.4V) can be converted to a stable 5V rail for powering a microcontroller and sensors. The 2.4MHz switching frequency enables the use of small inductors, saving PCB space in compact designs.

Industrial Sensors and Automation
In industrial environments, input voltages can vary due to long cable runs or fluctuating power supplies. The TPS63070RNMT's buck-boost topology ensures a stable output voltage even when the input is above or below the desired level. Its 2A output current can power multiple sensors, microcontrollers, and communication interfaces. The device operates over a wide temperature range (-40C to +125C), making it suitable for harsh industrial conditions. The high switching frequency reduces the size of external components, which is beneficial for space-constrained sensor modules.

Key Differentiators
- Wide input voltage range (2V-16V) (vs TPS630242YFF)
- Higher output current (2A) (vs TPS630242YFF)
- VQFN-15 package with exposed pad (vs TPS630242YFF)
Design Notes
For optimal performance, place the input capacitor (10uF) and output capacitor (10uF) as close as possible to the VIN and VOUT pins, respectively. Use short, wide traces for the power path and the switch node (SW) to minimize parasitic inductance and resistance. The inductor should be placed close to the SW pins to reduce radiated EMI. A solid ground plane is recommended to provide a low-impedance return path.
The VQFN-15 package has an exposed thermal pad that must be soldered to a copper area on the PCB for effective heat dissipation. For applications with high output current and large input-to-output voltage differences, ensure adequate copper area (at least 1 square inch) and consider thermal vias to the ground plane. The device's thermal shutdown protection prevents damage, but proper thermal design ensures reliable operation over the full temperature range.
Do not exceed the absolute maximum input voltage of 16V. Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. The enable pin should not be left floating; tie it to VIN or a logic high for always-on operation. When operating in PWM mode, the device can sink negative current on the output, which may require a load resistor to prevent output voltage rise if the load is disconnected.
